Flux integrated over the full spectral range of the C III, Si III, and Si IV lines (from top to bottom). The lowermost panel shows the flux cumulated over those lines. Fluxes are normalized using the quiescent spectra, averaged over all exposures in Visit A_fuv (blue), over exposures 1–4 in visits B_fuv (green) and C_fuv (red) for the C III and Si III lines, and over exposures 3–4 in visits B_fuv and C_fuv for the Si IV line. Vertical dashed lines are the transit contacts of 55 Cnc e.
